The US State Department publishes these advisories for your route. Thailand: Level 2 — Exercise Increased Caution (as of 2025-07-25). Review the country page for the specific areas and risks flagged before you go.

Transmission is often region-limited within a country (e.g. coastal vs highland zones) and varies by season. Discuss prophylaxis with a travel medicine clinician — the right antimalarial depends on the specific region, your medical history, and any medications you take.
Thailand (TH) requires every traveller to submit the Thailand TM6 Digital Arrival/Departure Card for entry — best done a few days before departure rather than in the airport queue. Without it, expect to be pulled aside at the border or denied boarding. Digital immigration card replacing the paper TM6 form. Complete before arrival. Apply at: https://tm6.immigration.go.th/
Thailand (TH) restricts or bans the import of: codeine, psychotropic substances, some sleeping pills. The risk is real — travellers have been detained at customs for over-the-counter products that are routine elsewhere. If you take any prescription medication, look up the active ingredient against the restricted list above before booking. Always carry the prescription bottle plus a doctor's letter naming the medication and the condition it treats. Adding your medications to your profile (optional) lets us tell you specifically which of yours match. Thailand FDA approval needed for some medications; carry prescription.
Thailand requires proof you'll leave before they let you in. At check-in the airline often asks for this — without it, they can deny boarding because the carrier becomes liable for flying you back. Easiest fixes, in order: (1) book a refundable return or onward flight, (2) use a one-way bus / train ticket out, or (3) buy a temporary onward-ticket reservation through a service like OnwardTicket. Have whichever you choose printed or on your phone before you reach the counter.
Thailand (TH)'s immigration officers can ask arriving visitors to show they have enough money for the stay — some travellers are never asked, others are pulled aside at the same border on the same day, so plan as if you will be.

Thailand requires 20,000 THB or equivalent per person Have a recent bank statement, a credit card with available limit, or a sponsor letter ready — the goal is to have a documented answer the officer can check in 30 seconds, not a debate.
Typical September conditions at BKK (Thailand (TH)): wet. Typical lows around 24°C, highs around 32°C, frequent rainfall (~296mm for the month). Expect frequent rainfall this month (~296mm typical). Pack a compact rain shell and a small umbrella.
